Unless Denver suffers injuries to key players, I'd count them in for sure. By staying at .500, the Nuggets did a good job of surviving a very difficult part of their schedule. Only 7 of their first 24 games were at home, so they've got 10 extra home games coming. And Denver is a solid home team.
And, yeah, I agree that the Warriors are almost a certain lock too, despite having missed the playoffs for so long. They are winning a lot on the road, and that's what playoff teams do. It's in part because they have good bench pieces. That helps down the stretch.
